Placing global stream flow variability in geographic and geomorphic contexts
River Research and Applications - Tập 22 Số 2 - Trang 149-166 - 2006
N. LeRoy Poff, Julian D. Olden, David M. Pepin, Brian P. Bledsoe
AbstractThe importance of hydrologic variability in sustaining natural riverine ecosystems is now well accepted. Over the last 15 years or so, many typologies and assessment tools have been developed to assist ecologists and managers in describing natural flow regimes in quantitative terms. In the course of this recent progress, however, some critical questions hav...... hiện toàn bộ
Redundancy and the choice of hydrologic indices for characterizing streamflow regimes
River Research and Applications - Tập 19 Số 2 - Trang 101-121 - 2003
Julian D. Olden, N. LeRoy Poff
AbstractThe utility of hydrologic indices for describing various aspects of streamflow regimes has resulted in their increased application in riverine research. Consequently, researchers are now confronted with the task of having to choose among a large number of competing hydrologic indices to reduce computational effort and variable redundancy prior to statistica...... hiện toàn bộ
Hydrogeomorphic processes affecting riparian habitat within alluvial channel–floodplain river systems: a review for the temperate zone
River Research and Applications - Tập 21 Số 7 - Trang 719-737 - 2005
Johannes Steiger, Éric Tabacchi, Simon Dufour, Dov Jean-François Corenblit, Jean‐Luc Peiry
AbstractHydrogeomorphic processes within alluvial river systems create, maintain and degrade riparian habitat. The dynamic interactions between water, sediment, aquatic–terrestrial landforms and biotic elements control the functional processes and biodiversity patterns within the riparian zone and, thus, contribute directly to their ecological integrity and societa...... hiện toàn bộ
Salmonid observations at a Klamath River thermal refuge under various hydrological and meteorological conditions
River Research and Applications - Tập 23 Số 7 - Trang 775-785 - 2007
Ronald J. Sutton, Michael L. Deas, Stacy K. Tanaka, Toz Soto, R. Alex Corum
AbstractThe Beaver Creek confluence with the main‐stem Klamath River was studied to assess salmonid use in a thermal mixing zone under various summer hydrological and meteorological conditions. Main‐stem flow releases from Iron Gate Dam ranged from 17 cms (615 cfs) to 37 cms (1320 cfs) during the study period and main‐stem water temperatures ranged from 19.5 to 26°...... hiện toàn bộ
Developing winter flow rating relationships using slope‐area hydraulics
River Research and Applications - Tập 27 Số 9 - Trang 1076-1089 - 2011
Spyros Beltaos
AbstractDespite recent advances in instrumentation and modelling methods, accurate determination of river discharge under an ice cover still requires direct measurement. Published flows at hydrometric gauging stations are based on interpolation between a few measurements that are carried out during each winter. The feasibility of using slope‐area hydraulics to deve...... hiện toàn bộ
Fluorescence analysis of dissolved organic matter in natural, waste and polluted waters—a review
River Research and Applications - Tập 23 Số 6 - Trang 631-649 - 2007
N. Hudson, Andy Baker, Darren M. Reynolds
AbstractDissolved organic matter (DOM) in aquatic systems originates from a range of sources. Some is allochthonous, transported from the surrounding landscape to the water body, and is derived from and influenced by the geology, land use and hydrology of its origin. Some is created in situ through microbial activity, which may provide an...... hiện toàn bộ
Resident perceptions of urban stream restoration and water quality in South Korea
River Research and Applications - Tập 34 Số 5 - Trang 481-492 - 2018
Chang‐Yu Hong, Heejun Chang, ‪Eun‐Sung Chung
AbstractThis research explores if individual preferences for the major functions of stream restoration processes correlate water quality variations in an urban watershed of South Korea. We use a set of results from an analytical hierarchy process model to rank the major stream restoration functions and compare citizens' preferences for “water quality” improvement d...... hiện toàn bộ
Quantifying and characterizing contemporary riparian sedimentation
River Research and Applications - Tập 19 Số 4 - Trang 335-352 - 2003
Johannes Steiger, Angela M. Gurnell, J. M. Goodson
AbstractFluvial processes of erosion, sediment transport and deposition determine the changing form and sedimentary structure of naturally adjusting riparian zones. Riparian sediment storage has both scientific and management importance in relation to: (i) the quantities of sediment that are involved; (ii) the quality of the sediment; and (iii) the dispersal of bio...... hiện toàn bộ
The Use of Stream Power as an Indicator of Channel Sensitivity to Erosion and Deposition Processes
River Research and Applications - Tập 31 Số 1 - Trang 16-27 - 2015
Simone Bizzi, David N. Lerner
SPATIAL AND TEMPORAL WATER QUALITY VARIABILITY IN AQUATIC HABITATS OF A CULTIVATED FLOODPLAIN
River Research and Applications - Tập 29 Số 3 - Trang 313-329 - 2013
F. Douglas Shields, Richard E. Lizotte, Scott S. Knight
ABSTRACTThe floodplains of lowland rivers contain diverse aquatic habitats that provide valuable ecosystem services but are perturbed when intensively cultivated. Hydrologic, water chemistry and biological (fish) conditions in five aquatic habitats along the Coldwater River, Mississippi, were measured for more than 4 years: the river, two severed meanders that func...... hiện toàn bộ
